The DI PP# xxx-xxx-xxx/000 all the way on the bottom of box 14, directly to the right of 3rd party sick pay (but in box 14), where do I enter that number?

[LisaBr]

On your W-2, Box 14, these entries are generally a catch-all for items where there is no other place to put them. 

Some of these entries are relevant more to the employer and you, not always to the IRS.

You should list the entries exactly as you see them and if there are no codes and you know what the entries are for, you can choose what they are from the drop-down box. 

If you don't know what they relate to, you can use Other - not on above list.  TurboTax will be able to know how it impacts your return.
